Study on spatial information system of soil and water conservation supervision in production and construction projects

Abstract:Based on the investigation and demand analysis of the status quo of soil and water conservation supervision of production and construction projects and spatial information technology,this research constructed a comprehensive supervision model of soil and water conservation, designed and developed a spatial information system for soil and water conservation supervision and management of production and construction projects, which covers the rapid acquisition of projects’ space location, on-line analysis, automatic identification to the system management of the construction projects.The results showed that:1)The system can realize the rapid discovery of disturbing spots in all construction projects in certain areas;the scope of water and soil conservation supervision extends from regional pointing to regional coverage;it can provide spatial data support for decision-making of soil and water conservation supervision department.2)The Spark technology introducted can batch processing the spatial data involved in the system, and satisfy the demand of mass vector data parallely and efficiently.3)The departments also can analyze the allocation of water and soil conservation measures for production and construction projects in different regions and evaluate the implementation and implementation of the supervision of soil and water conservation institutions at all levels through the statistical functions of the relevant departments.In conclusion,the system has completed the transformation of soil and water conservation supervision mode from manpower to information technology, expanded the coverage of soil and water conservation supervision, improved soil and water conservation efficiency and management capacity, and reduced soil and water loss caused by illegal construction projects.
